On the main timeline I also have a movieclip called 'world' (_root.world)

Inside 'world' I have four movieclips called 'pilot' and 'building1' and 'building2' and 'building3' (_root.world.pilot and _root.world.building1 and _root.world.building2 and _root.world.building4)

Inside 'pilot' I have many tweens on different fames (one tween on say frame 1-15, another on say 16-25 etc etc)

Basically when i click one of the buildings, i want it to play a certain tween whilst also changing the var mov to another number - so that when i click another building after the first one, it will play the tween according to what mov equals. I hope you understand.
